Whereas comics were printed on a paper in the past, it is now possible to produce digital comics thanks to the development of computer technology. However, it only came to be implemented on a monitor instead of paper and did not fully utilize a digital environment. That is because most digital comics or published comics have been made to be transferred in 'one-way' which means that contents of authors are transferred only to readers not vice versa. Recently, the notion of the 'interactive' in the digital contents takes its own shape even at the 'interactive way' of the communications change through the author and the reader's interactivity using the digital technology. As such, the study put more importance on the digital comics in a proper interactive story-telling structure and one of its category through the suggestion of the above and the soil where to develop the following study.

Small RFID tag antenna were fabricated on Si substrate and their physical and electrical properties were evaluated. With decreasing the size of tag antenna on Si substrate, small SMD-type RFID tags could be fabricated, which is very useful for PCB tracking. Firstly, tag antenna pattern and the electromagnetic properties were simulated with HFSS. The frequency was 13.56MHz, the line-width and line-gap were modeled in the range of $50{\sim}200{\mu}m$. S parameters, SRF, and Q value were calculated from geometry. When the line-width and line-gap were 100um and the loop-turn was 10, the SRF was 80MHZ and the Q value was ca. 9. When the microstrip antenna pattern of aluminum was fabricated by using DC sputtering, Vpp of ca. 1.6V was obtained when the reader-tag distance was 40mm.

In recent, the blood type waken the reader's interest in the field of movie, music, and education. Now, the blood type is far better than was anticipated in every aspects of life than a personal taste and appear as a familiar topic of story telling in modem life-style. Long time ago in Japan, the blood type was used to a casting of character and a consistent personality. In this study, the types of personality is combined with a blood type and devided with a frame of types. Also, personalities of character are observed and compared in a general animation which not applied a blood type. In particular, a personalities of family in animation are analized through a blood type and applied by character. Also, the blood types based on character of families get an appeal of audience. From now on, it will expect a variable analysis of animation, and needs for a continuous study not only blood type between families but relationship between blood types.

In this paper, we have implemented a ubiquitous healthcare system that can measure and check human's health in anytime and anywhere. The implemented prototype are composed of both front-end and back-end. The front-end have several groups: environment sensor group such as temperature, humidity, photo, voice sensor, health sensor group such as blood pressure, heart beat, electrocardiogram, spo2 sensor, gateway for wired/wireless communication, and RFlD reader to identify personal. The back-end has a serial forwarder to propagate measurment results, monitor program, and medical information server. The implemented sensor node constructs a sensor network using the Zigbee protocol and is ported the TinyOS. The data gathering base node is linux-based terminal that can transfer a sensed medial data through wireless LAN. And, the medical information server stores the processed medical data and can promptly notify the urgent status to the connected medical team. Through our experiments, we've confirmed the possibility of ubiquitous healthcare system based on sensor network using the Zigbee.

Currently RFID code systems are classified into ISO, EPC, uCode, KKR code, Mobile RFID code, and etc. According to RFID code systems, RFID system is changed. For various RFID code systems, it's difficult to make it to the network and permanence of RFID business. And the existing system isn't add new RFID code systems to RFID system, and change it efficiently. This paper is proposed to a system of Multi RFID code Identification Translation using Ontology. This system is able to identify code data from RFID reader using ontology build into the identifier info and translation info of RFID code systems, and translate to URN data. Therefore in case of extending and changing RFID code systems, we can add and change the identifier info and translation info of RFID code systems in ontology.

The Food is very important in our life, And the agricultural products are one of the most important food materials. For buying it, it's hard for the consumer to trust the agricultural products. That this reason, why they can't easily get the product information about agricultural productions. If you can get it, It is only mark of information about The country of production, They can not get reliable informations such as Producers, productions, residual pesticides, and soil conditions, etc. Accordingly, When consumers buy these agricultural productions, They want to provide reliable information. In this paper, using an RFID(Radio-Frequency IDentification) reader who reads RFID TAG attached to products. Then, Acquired Certification Number sent to a web server. To get the Production informations and Safety Inspection Information. The way that consumers can trust the Agricultural Products. These Traceability systems were implemented.

In this paper, we develop an application service of user authentication system using context awareness technology. The proposed security printer system service is applying 'NFC(Near Field Communication) technology', 'authentication system using communication with server, according to context awareness to application system. Our system extracts several context-awareness elements that happen through the user's printing with server communication. The proposed system property elements contain as print time, number of printing and name of document, etc. based on working memory operation as DB. This proposed system provide with context-awareness weight algorithm and analyzes the service which decides success or failure of user's printing. The develop app service is formed and applied when approved user who gets request. Approved user according to these context awareness tech will be provided with final service after authenticating again for the certain NFC card to reader. This results cab be contributed an authentication service based on context awareness weight algorithm and improved performance of management service in secure service applications.

In this paper, we studied the location estimation algorithm of a spatial 3 dimension which extend the location estimation algorithm of a plane 2 dimension in 2.45GHz band RTLS(Real time location system). We used TDOA scheme which need not a time of transmission information of the tag and estimated 3 dimension coordinates. Also, estimated intersection of hyperbolic curve to X, Y coordinate of the tag at 2D coordinates searching area, $300m\times300m$ and LOS propagation environments. And, we estimated Z coordinate ultimately using X, Y coordinate. The location estimation algorithm of a spatial 3 dimension satisfies the RTLS specification requirement, 3m radius accuracy. From the result, we confirm that the location of tag which similar to actual coordinate in the case to an ideal received offset. However, we verified that the location of tag which escapes from a radius 3m within error range when received offset increased. Therefore, as the future work we are consider enhanced location accuracy of a spatial 3 dimension in RTLS system which using the decrease scheme of reader offset or the discriminate scheme of the estimation location.

As for comics and animation, the specific gravity came to become still larger in all the art fields together with the importance in various image media now which is useful and goes the time of the 21st century new media. Especially the demand of users to the vision culture which develops day by day, Sensitivity Engineering Department is trying to realize the necessity for a sensitivity design acutely together. The influence of the comics which have toxicity most also in Japanese culture in a geographical position like South Korea on it, and animation is the actual condition in the reason which has reached from youth universally to the layer for years, to be inquired systematic to a Korean comics language. This reserch was conducted as we thought sufficient study on various situations are required, and among them, for the reserch of expressions of cartoons's characters, we've divided the expressions of characters that comes out in Japanese cartoons into catagories of "happiness, anger, sadness, pleasure" and "fear, astonishment and dislike" and based on these catagories, we've drawn out the minimum elements to express emotions in cartoon and prepared image-map by relating them with languages that express emotions of people and based on this, we've made a calculating tools on how our readers would read the expression languages. Samples of Japanese cartoons of which we've chosen for the purpose of drawing out the elements of expressions were limited to only published cartoons and we've made a foot steps for expression analysis of animation characters in the future.
